Flickering shading on alembic model when animated

[Joch1175]

Hello guys,
I’m doing an animation project with my friends recently.

We export animated alembic from Maya to Unreal.
But sometimes we get this flickering issue.

Does anybody have this issue before and know how to fix it?
Should be the mesh issue since we have this even at the lighting only mode.

Thanks,
Joseph

Hey! I hope this isn’t too late (or you’ve solved this issue already) but this fixed it for me: Light and Shadow for an Alembic Object ? Need help — polycount

Hope this helps!
